2010 TMR Impreza WRX STI Spec C
2010 will see the third evolution of the TMR Group N car based on the Subaru Impreza hatchback chassis. The TMR Engineering team working with a constant high level of feedback from a number of top Finnish drivers including our own resident test driver Tommi Mäkinen, have after also analysing countless feedback comments from our 2009 clients, produced a list of impressive improvements for the 2010 car.
The 2010 TMR Group N Impreza will continue with its ground breaking innovations as first seen in the previous models. Working within the FIA’s latest regulations, the engineering team at TMR have created and tested the new car to the utmost limits of durability and performance to produce the final 2010 product.
The 2010 Spec C car benefits from the 2009
Homologation changes, and features the lighter stronger body shell developed by TMR to enhance the car’s overall performance.
Aluminium bonnet makes front end of the vehicle lighter and improves maneuverability. Laminated glass is used in windshield and side windows. This lightens the upper section of the body, resulting in improved stability in cornering.
The new twin scroll turbo charger with roller bearings, seen for the first time on the 2009 model, has also been retained for use on the 2010 car, but now features the new TMR designed 33 mm restrictor in line with the 2010 regulations.
Improved mapping, with new full throttle gear shifting system, new anti lag strategies and a revised launch control system, have enabled the TMR Engineering team to produce increases in both engine power and torque to increase performance and most importantly driveability of the new car.
A recently formed co-operation with the French suspension specialist Bos has led to an all new suspension package for the 2010 car. Utilising the combined experience of TMR and the engineering team at Bos to design, test, and develop the new package, has led to major suspension and car handling improvements over an already proven 2009 car.
The 2010 car will feature an all new interior layout incorporating a new design driver data screen in the centre consol. The Gems GD25 is a 16 page colour display adapted to TMR specification to provide detailed information on
request. TMR have worked extensively on the aesthetics of the new interior to produce a high tech, but practical approach to the new layout.
